Re: Valve Job
Yeah .....if you mean seats ..then, yes, more than an hour and much more than $5.
I imagine that since you said 1 hour and $5 however, that you're referring to "seals". It will cost you more than $5 still ...but it's cheap. You need a compressed air supply, a fitting to plumb the air to the spark plug hole, and a tool from (what used to be called) the KD tool rack at your local parts store. If you have a decent piece of flat stock and a vise you can make your own.
You loosen and remove the respective rockers of the cylinder in question ...the air keeps the valve in place ...the tool allows you to compress the spring and remove the keepers .....you put your new umbrella seals (or whatever the 258 uses).....recompress the spring ...replace the keepers ..whack it to make sure that the keepers are in place correctly ...voila~ move to the next cylinder.
